I know 100miles each way. Decision taken out of my neighbours hands as he's got breakdown cover.

Just to close this down and thanks for everyones help. Had to call a breakdown service. They were unable to clear the ECR fault codes and car now to be transported from Skye to Inverness to the Audi dealer as they reckon no-one around here has the gear to fix it. Its my neighbours car and thankfully I have a VW. Really put me off Audi as a brand but Ill get over it Jon

sorry was about 10-14 days before new battery fitted

Hi thanks for prompt responses. I can't easily get a multimeter on the starter motor but there is absolutely no noise from it eg solenoid clicking or anything. Battery has been charged and also jumped from another car to no avail. I haven't coded in the battery as i don't have easy access to a device but Im told by several garages that the car should still start without doing that. I agree though it looks like the car has shut down and locked me out. I can't even get it to a garage

So AUDI A5 2015. left for 5 weeks came back to flat battery charged battery and was OK for 3-4 days then flat again (10y old) replaced battery with Tanya AGM wouldn't start or turn over. Lots of error codes tried to clear using OBD 11 PRO but it couldn't connect. disconnected battery and temporarily joined the car cables together to discharge capacitor tried a jump start checked and cleaned battery terminals temporarily removed the "shunt" connector from the negative When I turn the key it just starts list code after code but Ive not seen an immobiliser code. Been fixing cars for 50 y but never have seen this before HELP
